Final answer:
Blood from the confluence of sinuses travels to the transverse sinuses, then to the sigmoid sinuses, and finally into the internal jugular vein, leading back to the heart.
Step-by-step explanation:
From the confluence of sinuses, blood travels through a structured network of vessels and sinuses in the brain.
After collecting blood from the superior sagittal sinus, the occipital sinuses, and the straight sinus, it flows into the transverse sinuses. These then proceed to drain into the sigmoid sinuses, which carry the blood through the jugular foramen and ultimately into the internal jugular vein.
The internal jugular vein channels the blood alongside the common carotid artery, eventually leading to the brachiocephalic vein, and back towards the heart for reoxygenation in the lungs.
